Hindi Adaptation and Psychometric Validation of the Successful Aging Scale (SAS)

Gerontological research on successful aging has received the least attention in Indian culture, possibly due to a lack of psychometric tools to assess it among Hindi-speaking older adults. This study conducted the Hindi adaptation and psychometric validation of the popular Successful Aging Scale (SAS). Following translation and language adaptation, primary data was obtained from 136 older Indian adults drawn using a stratified random sampling technique. Quantitative data was collected on the Hindi-adapted version of the SAS along with WHO Quality of Life-BREF, Self-rated physical health (SRPH), General health questionnaire (GHQ-12), and Depression Scale (of DASS) for psychometric validation purposes. The Hindi version of SAS showed excellent internal consistency (r = 0.94). The significant correlation between the Hindi version of SAS and the criterion variables indicated significant construct validity (convergent and divergent) of the scale. The exploratory factor analysis identified two underlying factors: the engagement and the functioning aspect of aging.
